Here is how it looks for me:
root@chroot:~# touch "long file with spaces.mp4" root@chroot:~# echo "long file with spaces.mp4" >mp4file.txt root@chroot:~# cat mp4file.txt long file with spaces.mp4 root@chroot:~# ls -l total 4 -rw-r--r-- 1 root root 0 Mar 3 01:02 long file with spaces.mp4 -rw-r--r-- 1 root root 26 Mar 3 01:02 mp4file.txt root@chroot:~# fname=$(<mp4file.txt) root@chroot:~# ls -al "$fname" -rw-r--r-- 1 root root 0 Mar 3 01:02 long file with spaces.mp4 root@chroot:~# fname=`echo $fname | rev | cut -d. -f2 | rev` root@chroot:~# ls -al "$fname".mp4 -rw-r--r-- 1 root root 0 Mar 3 01:02 long file with spaces.mp4 What version of bash are you using? > ------------------------------------------------------ > > It is not: > > * a special character thing, > > * a carriage return thing, > > * a character case thing, > > * not helped with './' or '~/' added in front of the filename. > > * It's the same string in both spots. > > Any thoughts folks? > I am not sure about the overall problem, but I can say I would replace this: fname=`echo $fname | rev | cut -d. -f2 | rev` with this: fname=$(basename "$fname" .mp4) Regards, -Roberto -- Roberto C.
